The present invention relates to an improvement 1n refrigeratorconstructlon.

In the construction of refrigerators theV joints around the doors arediflicult to seal against the entrance of heat into the interior o therefrigerator.

An object of the present invention is to make a simple and leffectivedoor sealing construction for refrigerators.

In order to attain this object, there is rovided, in accordance with onefeature o the invention, a groove extending entirely around the dooradjacent the edge thereof in which a sealing strip is inserted andanchored.

These and other features of the invention will be more fully brought outin the following description and the accompanying drawin s, wherein:

igure 1, is a viewin perspective of a portion of a door made inaccordance with the present invention. v n 4 Figure 2, is a sectional,perspect1ve view through a door made in accordance with theV presentinvention, the door being shown in a closed position in a door openingof a re-` frigerator.

Figure 3, is a view, also in sectional perj spectlve, showing the methodof fastening the sealing strip in position. Figure 4, is a view in sideelevation of a staple used to. hold the sealing strip in place. Figure5, is an enlarged and cross sectional view of a sealing strip; and

Figure 6, is a sectional view illustrating modled means for fasteningthe sealing strip in position. j l Referring to the drawings in detail,a refrigerator door A is composed of frame members2 and 3 with aninterior enamel coated metal plate 4 held in osition b securing strips 5which engage t e outer` e ges of the plate 4 to hold it firmly inposltion. Sheets and 8 of insulating material are ailixed in f positioninteriorly of the door by means of strips9 and 10 in a customary manner.

A door cover plate 11 is enameled metal bent downwardly around its outeredge as at 12 to form a continuation of theouter edge, as at 12, toAform a continuation of the outer door covering about the edges of thedoor,

the edgethereof being bent inwardly as at 13 to closely engage the doorframe members 3. A groove 14 is cut in the wooden frame member 3 aboutthe entire door, closely adjacent the outer edge` thereof, beingpreferably cut to slope outwardly toward the outer edge of the door, asshown, to hold a sealing strip B 'outwardly adjacent the extreme outeredge of the door and against le inturned edge 13 of the door cover plateThe sealing strip By comprises a central core 16 of cushioning materialwith an outer covering 17 of fabric,'or -other suitable material. Thecovering 17 is wrapped about the core to closely encircle it, and issewed, or otherwise secured, as at 19, to provide an extension 18projecting outwardly from the body portion of th'e sealing strip. Thisprojectmg portion 18 is inserted in the grooves 14 in a continuous stripabout theentire outer edge of the door and is securely fastened inposition within the groove by driving staples 2Q, orother securingmeans, through the frame member to penetrate the portion of the sealingstrip inserted in the grooves 14. The outward sloping of the rooves 14,as shown, positions the rounded ody portion of the sealing stripvoutwardly toward the outer edge of the door, so that upon closing thedoor the sealing strip will engage the body of the refrigerator and bepartially flattened to have continuous sealing engagement with the bodyof the refrigerator and the inturned edge 13 of the door covering'plate11 com'- -pletely around the door opening.

The body of the refrigerator, which is of a well known ty e ofconstruction, is indicated in Figure 2. frame member 21 has framemembers 22 and 23 secured thereto. The outer Walls of the refrigeratorare covered with enameled plates 24 and 25. A strip 26 of wood issecured to the inner side of the frame member 21 to conform to theoffsetting of the door construction. The door does not seat closely inthe door opening as is clearly shown in Figure 2, being separatedtherefrom sufliciently to prevent condensation of moisture in thisportion of the refrigerator, as would occur i the door were arranged toeelt ti htl in the door opening. The inner enum` ed ing of the refrrator is indi- :ieted et 27 an is of any suitable construcon.- 5 In theforxn shownin Figqre 6' the'sheathg1g stnfp B 1s held 1n positlonbetween the ge o the plate 12 and the edge of the door.

d d h bod a re 'gerator oor aving a y por- 10 tion provided with laneedge faces,4 a resilient packi strip avin a rounded body portion rovi edwith a anfge adapted' to engage e lane edge faces o the door, and 15 anenamele metal sheathing forethe door having inturned edges formed toengage the flange carried by the packing strip whereby the atter isretained between the plane edge faces of the door and the nturned edgesof m the metal sheathing.

In testimony whereof I amx m si ature.
